[ExI] IQ and beauty

Why hasn't Evolution insured that everybody is beautiful? I can think of 2
reasons and they both involve sex:
1) Traits that we find attractive in one sex we may think ugly or grotesque
in another, so a gene that enhances that trait will not dominate the gene
2) Even if both sexes find a trait attractive the natural environment may
not agree; I'm thinking of the tail of a peacock which is a hindrance at
flight and a hindrance at everything except at finding a satisfactory mate.
If the tail gets much larger or more beautiful the bird will probably go
extinct in a blaze of gorgeousity.

made flesh. It was like a bird of rarest-spun heaven metal or like silvery
wine flowing in a spaceship, gravity all nonsense now." Alex- A Clockwork
